MUTCD Compliance Standards
State DOT Approved Signage
R10-3E signs are MUTCD-compliant regulatory traffic signs used to restrict turning movements during red signal phases at signalized intersections. Available in LED, fiber optic, and fluorescent formats, these signs help agencies manage traffic flow, reduce conflicts, and improve intersection safety across municipal, county, and state DOT roadway networks throughout the Midwest.


The R10-3e sign is a MUTCD regulatory sign within the R10-3 series that restricts specific turning movements, such as no left or no right turn, during a red signal phase at a designated approach. It uses a red circular slash over a turn arrow symbol and is typically mounted near the signal head to reduce conflicts with pedestrians and cross traffic.
